Yup. The new Kuiu Pro series is the shizzle. Love both my 3600 and 6000. Hang to my back like a monkey. Comfortable and love the layout.I was in the same boat(kinda still am), except I was narrowed down to Kuiu, Exo and SG.
It is my understanding that Kuiu has fixed many of the issues that used to plague their packs, but I still lacked 100% confidence in their products. Especially with the ravings of Exo and SG owners.
I have an Exo 4800 and SG Solo en route this week and plan to return whichever I like the least. I reccomend doing the same if budget allows. Even though both packs are probably great, one may fit you specifically better than the other
